AC Issues 2006 Expedition

[Mike Keenan]

I am trying to help my girlfriend out here... She has a 2006 Eddie Bauer Expedition with AC issues. When she starts it, the AC blows through the defrost vents. Within 10-15 minutes, it will start blowing through dash vents. Is this a vacuum issue somewhere, like a simple fix I hope?

Inspect the supply side vacuum line for any cracks or obvious leaks. You might even hear it whistling with a leak. Inspect all of the vacuum lines there in behind the battery area as well. Make sure the vacuum line is properly plugged into the hot water valve as well.
